Expedited Shipping to Italy

I seek information about expedited shipping to Italy. My package contains computer part that will be a replacement for an existing computer. Therefore, it is needed most urgently. The part is very light, and weighs less than one pound. It is also small, and will fit in a box smaller than a shoe box. My questions for your company include how quickly can this package be delivered to Milan? This part is critical to the company's manufacturing process and they need it just as soon as is possible. I am willing to pay extra if that is what it would take to get this part delivered any faster. How much will this expedited shipment cost? Are there any restrictions on pickup or delivery? Since this is a replacement part, are there any taxes or fees? Also, if you have information on customs duties or other restrictions, I would like information on that as well. Thank you for your prompt reply.
